This is a math-science integrated unit about spectrographs. Learners will find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, the students will build their... (View More) own spectrographs in groups and research and design a ground or space-based mission using their creation. After the project is complete, student groups will present to the class on their trials, tribulations, and findings during this process. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant. Requires the use of ALTA II spectrometers (which may be... (View More) borrowed from the Lunar and Planetary Institute or purchased online) and Mars soil simulant. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

Learners will be introduced to the concepts of error analysis, including standard deviation. They will apply the knowledge of averages (means), standard deviation from the mean, and error analysis to their own classroom distribution of heights. They... (View More) will then apply this knowledge to data from the Student Dust Counter (SDC) onboard the New Horizons mission to determine the issues associated with taking data, including error and noise. Note: Updated links to the Student Dust Counter Data Viewer and website are provided under Related & Supplemental Resources (right). (View Less)

Learners will compare known elemental spectra with spectra of Titan and Saturn’s rings from a spectrometer aboard the NASA Cassini spacecraft. They identify the elements visible in the planetary and lunar spectra. The activity is part of Project...

Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The...

Learners will interpret spectral graphs to determine the atmospheric composition of Earth, Venus, and Mars, and then mathematically compare the amount of the greenhouse gas, CO2, on these planets. Students will brainstorm what things, along with... (View More) greenhouse gases, can affect a planet’s temperature. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More) "spectral fingerprints" of elements. They learn to identify each image as unique, yet part of a group containing recognizable similarities.
